The book 5 Killer habits is inspiring in lots of ways. I definitely recommend this as a "must read". It's free of cost on kindle, so anyone can read it. The most notable part, is that, the profit made from this piece of literature will help in the education of girls.
The crux of the books - is to become a better human. It starts from sleeping habits to questioning the truth. To become enlightened and not be ignorant of the people and also the world as we know it.
The chapters are all clearly organized and lucidly written. Though, there are thoughts of the author that some might not agree with, but overall it leaves a good impression. The author promotes free speech and unyieldingness in expressing our opinion. All in all, quite a positive read.
